ADJUSTING-PIN FOR MOLDlNG-FLASKS..

SPECIFICATION forming part of Letters Patent No. 475,088, dated May 17,1892. Application filed November 20, 1891. Serial No. 412,f554=. (Nomodel.)

- To all whom it may concern:

Be it known that I, ARCHIBALD MONTGOM- and Ireland, and a residentofPhiladelphia, Pennsylvania, have in vented certain Im provements in Adjlisting-Pins for Molding-Flasks, of which the following is aspecification.

One object of my invention is to so construct the pin and socket used inconnection with the cope and drag of a moldingflask that said cope anddragmay be accurately adjusted in respect to each other, a furtherobject being to so construct the parts that the pin will properly enteror leave the socket, even if the cope happens to be tilted, as inshaking out after molding. These objects I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in which Figure 1 is a perspective view of parts of the cope and drag ofa molding-flask, showing the application of my improved adjusting devicethereto. Fig. 2 is a longitudinal section of part of the cope and dragof the flask with the adjusting devicein position thereon. Fig. 3 is afront View, partly in section, of the socket-plate; and Fig. 4 is a planview of said socket-plate with the pin in section.

A represents part of the cope, and B part of the drag of a molding-flaskof the usual construction. To the cope is secured a bracket .D, having aprojecting boss at, in which is a vertical opening for the reception ofthe upper portion 1) of the adjusting-pin, which fits within the openingin the boss at, but can be turned therein by manipulating the head d ofthe pin, vertical movement of said pin in the boss, however,beingprevented by means of a transverse key f, which passes through openingsin the boss and engages with a circumferential groove g, formed in theupper portion of the pin, as shown in Fig. 2, the openings and groovebeing, by preference, square or flat-bottomed, so that an ordinary nailwill serve as a key. The lower portion h of the pin is eccentric inrespect to the upper portion and enters an opening 2' in thesocket-plate m, which projects from a bracket F, secured to the drag Bof the flask, this opening being beveled or flared from top to bottom,as shown in Figs. 2 and 3, so that the pin will properly enter or leavethe opening even if the cope is not held in a horizontal position, sothat the raising or lowering of one end of the cope in advance of theother or the tilting of the cope, as in shaking out the sand aftermolding, will not cause the pin to bind in the socket or prevent it fromentering the socket. The opening 11 in the socketplate m is of thedouble-V form illustrated in Fig. 4, so that the pin it bears upon thewalls of said opening either at the points x a: or at the points 00 as,there being always two points of contact and a flrrn bearing of the pinagainst the walls of the opening.

Owing to the fact that theportion h of the pin which enters the openingi of the socket-plate is eccentric in respect to the upper portion ofthe pin which turns in the boss at, rotative movement of the pin in saidboss will cause longitudinal or lateral movement of the cope or drag ofthe flask relatively to each other, so that by a proper adjustment ofthe pin the cope and drag may be caused to accurately register one withthe other, as required.

Other means than the brackets D and F may be used to secure the boss andsocketplate to the cope and drag of the flask, if desired; but saidbrackets are preferred.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The within-described adjusting device formolding-flasks, said device comprising a,

pin having one portion eccentric in respect to the other, a boss inwhich one portion of the pin is free to turn, and asocket-plate havingan opening for the reception of the other portion of the pin,substantially as specified.

2. The within-described adjusting device for molding-flasks, said deviceconsisting of a pin having one portion eccentric in respect to theother, a boss in which one portion of the pin is free to turn, asocket-plate having an opening for the reception of the other portion ofthe pin, and brackets whereby said socketplate and boss may be securedto the drag and the cope of the flask, substantially as specified.

3. The within-described adjusting device for molding-flasks, said devicecomprising a pin having one portion eccentric in respect to the other, aboss in which one portion of the pin is free to turn, a socket-platehaving an opening for the reception of the other portion of the pin, anda transverse key passing through the boss and engaging with a groove inthat portion of the pin which turns in said boss, so as to confinethepin vertically thereto, substantially as specified.

4. The within-described adjusting device for molding-flasks, said devicecomprising a pin, a boss adapted for the reception of one portion'ofsaid pin, and a socket-plate having an opening beveled or flared fromtop to bottom in all parts and adapted for the reception of the otherportion of the pin, substantially as specified.

5. The within-described adjusting device for molding-flasks, said devicecomprising a pin having one portion eccentric in respect to the other,aboss in which one portion of said pin is free to turn, and asocket-plate having ARCHIBALD MONTGOMERY.
